Abstract: This application provides a fault detection method, an apparatus, and a system. The method includes: A transmit end apparatus includes, when sending a border gateway protocol BGP message used for advertising a route, a bidirectional forwarding detection discriminator BFD discriminator configured by the transmit end apparatus, to trigger a receive end apparatus to automatically create an SBFD session used for detecting reachability of a target object associated with the transmit end apparatus, where the target object may be a locator address or a next-hop address of the route.
